Older vessels has smaller (or no) finance costs as they have been paid off and written down. Thus they can accept lower T/C rates, which makes them easier to fix. (“Fix” as in Broker speak, not mechanically)
BTW: That they burn more fuel is a negative for the Charterer when on T/C terms, but may be balanced out by lower charter costs…
The Master of New Diamond has pleaded guilty, paid a fine and is now free to leave Sri Lanka:
So ends a case of “legal extorsion” for this time. The P&I Club pay the fine and the Master can go home. (But it will embolden the Government in other countries to do the same)
Really impressive that she made it in one piece. The Indian and Sri Lankan Navy/Coast Guard deserve a lot of credit in their response to this emergency, as do the salvors for getting her secured enough to survive the long tow. Truly averted a potentially catastrophic environmental disaster.
